Range
The Range parameter defines how “far” you want the TrawlEye to detect echoes. The range is defined from a selected start range, and down to a value less than the current bottom depth or a distance in
horizontal direction in the water. A better resolution is achieved using the shorter ranges.
With a trawl opening of 5–6 meters, you should select a 10m or 15m range value.
If you want to configure a PX TrawlEye sensor that is version 2.12 or higher, you can select a dual range. With dual range, 50% of the echogram resolution is used on the first 5, 10, 15 or 20 meters; the rest of the resolution is
used on the rest of the echogram: that is 95, 90, 85 or 80 meters.
